Bag structure with pocket



R. M. Fox BAG STRUCTURE wTH POCKET Filed Oct. 5, 1955 Piau United StatesPatent() Scott & Sons Company, Marysville, Ohio, a corporation of OhioApplication October 5, 1955, SerialNo. 538,556 L 2 Claims. (Cl. 229-56)This invention involves the construction of multiply paper bags andparticularly the provision of a special pocket formation to carry cardsand instruction leaets and the like for the purchaser of the bag.

The object of the invention is to provide a multiply bag structureintegrally embodying a pocket formation of ample size and readilyaccessible from the outside.

Further objects of the invention particularly in the filling of thepocket during the manufacture of the bag will appear from the followingspecification taken in connection with the accompanying drawing inwhich,

Fig. 1 is a perspective view of the upper portion of the filled bag asdelivered to the customer and showing the integral pocket as it appearsunopened;

Fig. 2 is a perspective view of the said upper part of the bag with thepocket torn open and the contents in course of removal; and

Fig. 3 is a similar view on larger scale of the top of the bag in courseof formation of the pocket and insertion in it of the cards, leafletsand the like.

The bag 5 shown in the drawing is large and formed of rather heavymultiply paper suitable, for instance, for carrying granular materialsuch as seeds, fertilizer and bulk products. As manufactured the bag isfirst before lling closed at one end, preferably the top 6, and is alsoprovided with the integral pocket formation generally designated 7 andshown located at the top of the bag in position to be closed by theclosing of the top end 6. The pocket is thus provided with its contentsprior to the closing of the corresponding end of the bag and theresulting structure merges the pocket as an integral part of themultiply assembly, being formed between outer and inner plies,preferably between the outermost ply and the one next to it.

As illustrated in Fig. 3, there are four plies 10, 11, 12 and 13, each acomplete tubular bag blank and they are nested together with their endsin register at 15 at the top and at the bottom (not shown) and theirseams preferably are out of register. They also are cemented together ina manner tending to favor the proper formation of the gussets 14, 14 bythe panels 16 and 17 on one side and 18, 19 on the other.

Bags of this type are often used in packaging fertilizer, seeds and thelike, where it is desirable to furnish with the material instructionsand explanations as to the uses, manner and frequency of application aswell as cards to be filled in and mailed to the manufacturer. The mainpurpose of the present invention is to supply with the bag a meansintegral therewith for carrying the booklets,

leaflets and the like bearing the desired directions andV information.

This is provided by a pocket structure 7 positioned as desired andpreferably located at the top and formed between the outermost ply orlamination 10 and the next one 11 (Fig. 3). The interface between theselaminations has the surfaces cemented or bonded together along 2,867,372Patented an. 6, 1959 ICC a U-shaped pattern by lines of adhesive areas25 and 26 running vertically and at the bottom by a line of adhesiveareas 27 running horizontally.v n

`At these areas the adhesive may be applied in spots or strips to formthe U-shaped pattern surrounding three sides of the pocket 7 but leavingthis area between laminations open at 20 at the upper end 15 of the bag;y

Before closing this upper end, the printed matter, pamphlet,instructions, or return postcard etc., Vare inserted into the pocket 7through the l,endy opening 20 ofthe pocket between the laminations 10and 11. The pocket 7 may then be closed by adhesively spotting the edgesof opening 20, or preferably the closure strip 31 is added at the entireupper end of the bag and sewed tight with the stitching 32. The contentsof the pocket 7 are securely entrapped in the now closed pocket formedin the bag structure.

To make the contents of the pocket easily available to the purchaser,the outer lamination 10 along vertical lines 34, 35 joined at 37 nearthe center of the pocket is scored, for instance, in the form of a tab36 which may be lifted by tearing it upward to open the pocket 7 asshown in Fig. 2.

Suitable guide markings and instructions are printed on the outersurface and thus the pocket with its contents is inexpensively includedwithin the usual bag structure, either filled and closed by the bagmanufacturer or supplied open to the filling and marketing company to besubsequently filled and closed by the latter.

There are no projecting parts, the surface of the pocket 7 is perfectlyplain and continuous with the surface of the outermost ply. The bagstructure is complete and the contents of the pocket 7 are separatedfrom the material in the bag by all the inner laminations. A part of thebag structure is simply cemented off and provided with its enclosures,the corresponding notations of the outer surface having been embodied inthe regular surface marking and design.

The pocket contents ar'e not limited to printed matter but may include,for instance, any other loading such as envelopes of accessory materialor any devices pertinent` to the sale or use of the bag contents.

The appearance is neat and compact (Fig. l) and the pocket is locatedforready access at the top either by the removal of the closure strip 31or by lifting of the tear tab 36.

While the invention has been described in connection with a specificembodiment it is not confined thereto but is intended to covermodifications thereof within the scope of the appended claims.

I claim:

1. A multiply bag having two ends, one of which ends is closed prior tofilling the bag, the other end to be closed subsequent to filling: alateral row of fastening means at said one end maintaining said one endclosed; means, between and including portions of the outer ply and nextinner ply, adjacent said one end of one side of the bag constituting acompartment, said means also including bonding material joining saidouter ply and said next inner ply to constitute at least one lateraledge of the compartment spaced away from said one closure of the bag adistance no greater than a position approximately midway between the bagends, the other lateral edge of said compartment being provided by saidlateral row of fastening means at said one closed end; a`
